Dianna Agron is really red hot on the red carpet as she arrives arm-in-arm with designer Michael Kors at the 2011 MET Ball held at the Metropolitan Museum of Art on Monday (May 2) in New York City.

The 25-year-old actress wore a ruby red gown from Michael Kors Collection to the big event, which celebrated the opening of the “Alexander McQueen: Savage Beauty” exhibition, featuring the late designer’s iconic work.

Dianna has been busy filming a few episodes of Glee around the Big Apple.

Psst, don’t forget — I Am Number Four is on DVD and Bluray on May 24th!
